Abstract

The invention discloses a formula and preparation method of organosilicone-free easy defoaming polyurethane paint for clarinets. Hydroxyl polyacrylic resin, an isocyanate adduct, polyketone resin, 1,6-hexamethylene diisocyanate and a matt trimer curing agent are the main film-forming substances of the paint, the materials undergo a reaction to produce a film through crosslinking, ethyl acetate, n-butyl acetate and cyclohexanone are main solvents for dissolving the resin, 1 / 16s nitrocellulose is used to adjust the viscosity of the paint and is easy to construct, non-matt wax slurry can improvethe paint feeling, fineness and scratch resistance, high-efficiency matting powder is used to adjust the luminosity of the paint and reduce light pollution, and a defoaming polymer solution (withoutorganosilicone) is the main additive to eliminate the bubbles of the paint and can change the surface tension of the bubbles to fast break the bubbles. Through reasonable combination of various components, a solvent evaporation rate is reasonable and excellent film-forming properties are obtained. The organosilicone-free easy defoaming polyurethane paint is good polyurethane paint.

Description

technical field [0001] The invention relates to the field of chemical paint manufacturing, in particular to a formula for improving the defoaming performance of clarinet musical instrument polyurethane paint without organic silicon and a manufacturing method thereof. Background technique [0002] The polyurethane paint for clarinet musical instruments on the market now generally has the problems of high viscosity and unsatisfactory defoaming effect. After stirring, a large number of bubbles are prone to appear, and it needs to be left for a long time to defoam, which will affect the construction time of polyurethane coatings and easily affect the clarinet. The beauty of the instrument. At the same time, polyurethane paints that are easy to defoam generally contain organosilicon compounds, which not only easily pollute the environment, but also affect the leveling performance of the paint when it is formed into a film, resulting in the unsightly appearance of clarinet instrum...
